Disclaimer: This is not a listing of all code sections involving building or utilities which involve this subject, but only the sections most often questioned. Refer to the 2013 Kentucky Residential Code book for information not listed in this handout and for other requirements of the building code. (This is not a guide to building pole building projects for commercial projects. For commercial projects you may be required to contact an architect or engineer for help with your design, depending on the project’s size.) Design Criteria: The following minimum design criteria apply to Pole Building Structures requiring building permits in Hardin and Larue County as specified in the appropriate tables of the 2013 Kentucky Residential Code, Second Edition, February

2014. There have been some code changes involving Accessory Structures which may be new to homeowners, builders, and suppliers in this area. This document addresses code requirements for Pole Building Structures as accessory structures. Clarification #1: For building code purposes most structures which are pole building type structures, and which are commonly used for open sided carports, shelters, garages, workshops, small agricultural animal barns and shelters, equipment sheds, storage buildings, etc., are determined to be residential Accessory Structures per the 2013 Kentucky Residential Code. Agricultural buildings, barns, carports, fences not over 7 feet in height, livestock shelters, private garages, retaining walls, sheds, and stables are determined to be occupancy Use Group-U in the

2013 Kentucky Building Code (Sec. B312, Utility and Miscellaneous Group U). Many pole building structures are commonly referred to as “pole barns” locally. Clarification #2: Accessory structures, larger than 200 square feet in size, are required to have a building permit prior to starting any type of construction on the project.

Building Code Clarification Handout, #2013.01, October 2013

POLE BARN PROJECTS; POST AND FRAME STRUCTURES Page 12 of 13 The building code now has a specific section which addresses “Pole Barns” or “Post and Frame Structures” all in one Section 324, the code sections defined in this document apply to these types of structures:

Agricultural buildings, barns, carports, livestock shelters, private garages, retaining walls, sheds, and stables are determined to be occupancy Use Group U in the 2013 Kentucky Building Code (Sec. B312).

Open sided carports, shelters, garages, workshops, small agricultural animal barns and shelters, equipment sheds, storage buildings, etc., are determined to be residential accessory structures per the 2013 Kentucky Residential Code. ( Sec. R202).

The scope of this document covers a minimal size one-story structure on a flat prepared subgrade with soils bearing capacity of 2000 psi or better. Other conditions such as: poor soils; sloping land; lofts or second story wood floors; etc. added to a building, or other conditions not described in this document, will require other code requirements not addressed in this document. The building must meet the 2013 Kentucky Residential Code. 20. Accessory Structure. (R202) Definitions. A structure not greater than 3,000 square feet in floor area, and not

over two stories in height, the use of which is customarily accessory to and incidental to that of the dwelling(s) and which is located on the same lot. (Note: This term describes structures commonly used as garages, carports, cabanas, storage sheds, playhouses, tool sheds and garden structures. The structures all contain uses that are incidental to the primary use, which is the dwelling unit, and the activities that take place in accessory structures occur as a result of the primary building. Their use is secondary or minor in importance to the primary residence.) In order to avoid having to build fire resistant rated walls, rated for exposure to fire from both sides, locate the accessory structure no closer than five feet from any other structure on the same lot. (Table R302.1(1)).

21. Applicability (R101.2 Scope) The 2013 Kentucky Residential Code applies to one-and-two family dwellings up to 3

stories above grade with separate means of egress and their accessory structures. C. Building Permit Required and Related Inspections Information The accessory structure must comply with the building setback requirements from property lines as well as from utility and drainage easements as detailed in the Hardin County, Kentucky, Development Guidance System (zoning ordinance). When applying for the permit, the Owner will provide to this office the distance from all sides of the new structure to the nearest property lines. The permit clerk will assist the owner in determining the minimum setback distances at time of applying for the building permit. Structures cannot be located closer to the property lines or streets than the setback distances allow. A residential accessory structure would also be required to meet the limits of the subdivision restrictions which govern the property it is located on. When in Larue County use the Land of Lincoln Planning & Zoning guidelines for the setbacks. 22. An approved building permit is required to be obtained from this office before the accessory structure is

placed, delivered, installed, set, constructed or built on the property. (R105.1). A permit is not valid until the fees prescribed by law have been paid. (R108.1). The applicant must state on the permit application, what the use of the building will be for.

Building inspections are required to be made on the project when a building permit is issued. It is the duty of the permit holder to notify the building inspector when work is ready for inspection at the various stages for the footing, framing, and final inspection. It is the duty of the permit holder to provide access to and means for inspection of such work for the inspections. (R109.3), & (R109.4). Inspections are made on a daily basis Monday through Friday only. The inspection must be requested 24 hours in advance of the weekday date the inspection is requested. Inspection calls received after 9:00 a.m. will be scheduled for the next business day. Footing inspection (foundation inspection) must be approved, prior to pouring concrete and prior to backfilling posts. (R109.1.1) At the time of requesting the framing inspection, the checklist begins with the assumption the required Footing/Foundation Inspection has already been requested by the owner and approved by this office. If there are any violations left not corrected on the footing inspection, the framing inspection cannot be performed.
